Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring stereochemical control. Its protected amine and carboxylic acid functionalities make it ideal for peptide coupling and heterocycle formation. Commonly employed in the preparation of central nervous system agents, including antidepressants and antipsychotics, due to the piperidine scaffold’s prevalence in neuroactive compounds. The Cbz group allows for selective deprotection under mild conditions, enabling stepwise assembly in complex molecule synthesis.
